Are  referring to  the fact  that  I would  prefer to  use a  manifest
constant versus  sysconf or looping until  a fit is found?   Clearly I

You  can't just  call  it once;  the hostname  can  change during  the

No, I don't -- I just think it is a bug.  One which is easy to fix for
the single-threaded case.

As I said in an earlier message,  I appreciate that.  I also happen to
believe that it has been misapplied here.
